The conformations of 3-pyridinoyl indoles, which are intermediates of 5-fluoropentyl-3-pyridinoyl indole, were investigated using their X-ray crystal structures. All derivatives existed as s-trans conformers. A pseudo-planar conformation was observed in the 2'-yl isomer of 3-pyridinoyl indoles. On the other hand, twisted conformations were observed in 3-pyridinoyl 2-methylindoles. The conformations of these compounds in solution were also investigated using VT-NMR.

Aryl ketones can be synthesized conveniently by a palladium catalyzed addition of arylboronic acid to nitriles in aqueous triflic acid. This catalytic system was extended to the addition of unprotected indoles to nitriles under a slightly modified condition to produce 3-acyl indoles in good yields.

An efficient palladium-catalyzed synthesis of 3-acylindoles using free (N-H) indoles and nitriles has been developed. The acylation reaction proceeded well under the Pd(OAc)2/2,2′-bipyridine system and with d-(+)-camphorsulfonic acid as the additive. A possible mechanism involving carbopalladation of nitriles and subsequent hydrolysis of ketimines is proposed.

The synthesis of some C-seco analogs of ellipticine (4-7 and 10-16) is described via the coupling reactions of various substituted indoles with nicotinic acid chloride hydrochloride, 3-acetylpyridine and isonicotinic acid chloride hydrochloride.
